New Delhi: Vitamin B12 plays a key role in producing brain chemicals that affect mood and other brain functions.
Vitamin B-12 (also known as cobalamin) plays a crucial role in the formation of red blood cells, cell metabolism, nerve function, and the production of DNA.
Some common symptoms of Vitamin B12 deficiency include strange sensations, numbness, or tingling in the hands, legs, or feet, difficulty walking (staggering, balance problems), anaemia, difficulty thinking and reasoning (cognitive difficulties), memory loss, weakness, or fatigue.
“Vitamin B-12 and other B vitamins play a crucial role in producing brain chemicals that affect mood and other brain functions. Low levels of B-12, as well as other B vitamins like vitamin B-6 and folate, may be linked to depression,” according to doctors.
The deficiencies can result from poor diet or difficulties in absorbing the vitamins consumed. So, maintaining an adequate B-12 level is essential for overall well-being, including mood regulation.
Vitamin B12 is majorly found in poultry, meat, fish, and dairy products. It is available as an oral supplement, as injections, or nasal spray.
People who consume a vegetarian or vegan diet may be more prone to deficiency as plant foods do not contain vitamin B-12. The elderly and people with digestive tract conditions that affect the absorption of nutrients also are susceptible to vitamin B-12 deficiency.
While research is ongoing, studies suggest a link between low B12 and depression, with some showing improvement in mood with B12 supplementation.
However, it's important to note that mood swings can have many causes, and a doctor should be consulted to rule out other factors and determine if a B12 deficiency is present, said doctors.
